About what?  What are you trying to do?  Do you have taxable income?  Are you trying to prepare a tax return?  Trying to register for the stimulus funds?  Please explain.

I am trying to do my taxes. My previous employer went bankrupt. 

if there is no one left at your previous employer to contact, then contact the IRS and ask them to send the information on your income that should have been filed by the employer.  Don't wait - there has been a delay in the due date so you have some time, but call the IRS today.

W-2's come from your employer, and they have until Jan. 31 to issue it.  Some employers allow you to import the W-2 through the software, but for security reasons you still need information from the actual W-2 to import it.  You might need to phone, email and/or snail mail an old employer to make sure they know where to send your W-2.

You can get a wage and income transcript from the IRS:  It will not show the actual W-2, 1099’s, etc, but will show the income information the IRS received.  It will not, however, show your state information. It will only show the federal information.
